Abstract
A system and method for drying individual biomass units. Turbine exhaust heats ambient air to produce heated air, which passes through a conveyor system that carries a quantity of biomass product to an endpoint collection area. Heated air with fine product particles is ducted to a series of cyclonic particle separators and collected.
Claims4
